Turns out I was a bit off, as it was only 3/4 decks that had Sovereign at that point. Ended up going 13-2 in matches today over 5 drafts by forcing some combination of RW aggro (edit: Single Elim queues).
Deck 1 (3-0)
Deck 2 (2-1)
I maindecked the Price of Process (and had a Magus of the Moon in the side) and both were great every match. Everyone seems to have a nonbasic or two at the least (even the mono colored decks have things like Cradle/Karakas/Port/etc) and in some matchups it was even better. Ended up losing to a more aggressive W/b deck.
Deck 3 (3-0)
Rolled through this one. Archangel went nuts with Soldier of the Pantheon once, so that was cool.
Deck 4 (2-1)
Ended up losing the finals to that smokestack/upheaval deck I mentioned. I'm pretty sure I punted it.
Deck 5 (3-0)
This one wasn't nearly as aggressive as the other builds, but it taxed the opponents more with hokiri, riders, geddon and zo-zu.
So after a long, long day of drafting I've come to the conclusion that whichever poster it is that's been harping on taking this route is absolutely correct. It crushed all the decks that were trying to abuse reanimate spells like Necromancy and Animate Dead as well as the ones ramping out Terastodon, Eldrazi, or Avenger of Zendikon. It had the edge on the mono-red decks I played with the consistently late Paladin en-vic and Silver Knight as well as the B/G decks with Knight of Glory, Mirran Crusader, and Hand of Honor. You're too aggressive for the blue based control decks to keep up (won multiple games through both wrath and day of judgment) and have too much reach and removal for a lot of the GW or GR aggro decks (they are a bit slower but bigger, but by the time they take over your reach should finish it off).
The card I was most impressed with was Imposing Sovereign by far. It was always good, even if it was drawn later. It was directly responsible for at least two of my wins, forcing opponents with Sneak Attack and Obzedat to be negating large aspects of their best cards. It was also partially responsible for 2 others - one when my opponent spent turn 6 casting big Elspeth for 3 tapped creatures letting me Hellrider for the win and a similar set up vs an Avenger of Zendikar.
The 2nd most was Chaos Warp. I turned a Karn into a Ratchet Bomb, a Jace into an Island, and a Birthing Pod into nothing.
Both of those cards were picked up super late initially in the drafts and I don't think they should be.
Give forcing W based aggro a try next time out. It was a lot of fun to play also.
